I'm seeing some very strange behavior on one of our storage servers recently, 
and am wondering if anyone else has been experiencing similar issues.  I think 
it may be related to InfiniBand somehow, but not sure.  Unfortunately there 
are no error messages in the logs of any kind.  But network traffic out of one 
or more interfaces just stops, or some traffic (ping e.g.) will work, but 
ssh/tcp won't.

Seen with both 2.6.32-431 and 2.6.32-358.23.2, and I think 2.6.32-220.23.1.
